More Frytful Scares
It was a dark and stormy night. A secret message arrived addressed to Rutherford & Fry from a mysterious woman called Heidi Daugh, who demanded to know: "Why do people like to be scared? For example, going on scary amusement park rides and watching horror movies that make you jump.” What followed was an investigation, which would test our intrepid duo to their very limits. They explore the history of horror, starting with its literary origins in the Gothic fiction classic 'The Castle of Otranto'. Adam challenges Hannah to watch a horror film without hiding behind a cushion. She quizzes horror scholar Mathias Clasen to find out why some people love the feeling of terror, whilst it leaves other cold. Sociologist Margee Kerr and psychologist Claudia Hammond are also on hand to explore why scary movies are so powerful and popular. Then Rutherford and Fry investigate the more physical side of fear, when they delve into the history of roller coasters to investigate why we enjoy being scared. Never ones to shy away from a challenge, the pair attempt to channel their inner adrenaline junkies with a trip on one the UK's scariest roller coasters at Thorpe Park. David Poeppel from New York University studies the science of screaming, and we discover what makes screams uniquely terrifying. Plus, psychologist and broadcaster Claudia Hammond describes some early experiments which tested how fear affects our body. This episode is a remake of two earlier broadcast episodes.

Back to The Sinister Hand
Why are some people left-handed, whereas the majority are right handed? Rutherford and Fry revisit The Sinister Hand episodes to further investigate handedness in humans and animals. They considered cockatoos, chimpanzees and Hannah's dog, Molly, to discover that humans are unique, with just one in ten of us being left-handed. They ask if there is an evolutionary reason for just 10% of the human population being southpaws Hannah talks to primatologist Prof Linda Marchant from Miami University about Neanderthal teeth and termite fishing. Adam consults handedness expert Prof Chris McManus from University College London. He's been trying to track down the genes responsible for whether we're right or left handed. And what about left-handed brains or eyes or molecules? Prof Andrea Sella explains handedness, or chirality, at the molecular scale and why when we consider Thalidomide, something seemingly so trivial can be extremely important. They also explore the left-handed brain. Some researchers point to a link between left-handedness and impairments like autism or dyslexia. Others claim that lefties are more creative and artistic. So what's the truth? The team consults Professors Sophie Scott, Chris McManus and Dorothy Bishop to find out. This episode is an updated version of two earlier broadcast episodes.

A Weighty Matter Part 2
The doctors continue their investigation into gravity, and answer Peter Fraser’s question: Is dark matter a proper theory or just a fudge to fit existing 'proper' theories to otherwise inexplicable observations? Whilst scientists are pretty convinced our understanding of gravity is largely correct, there are still some significant gaps. Namely, given the way galaxies are observed to behave, around 85% of the matter that they think should be in our universe. So where – and, as importantly, what – is it? Cosmologist Andrew Pontzen introduces the evidence from our observations of the cosmic microwave background, light leftover from the Big Bang, which indicate that dark matter exists. However, this evidence alone is not enough for science. Physicist Chamkaur Ghag is trying to find particles of dark matter here on Earth. Unsurprisingly, no-one is quite sure where these critters are hiding in the particle zoo of protons, neutrons, electrons, quarks, bosons, muons and the rest – or even what they look like. One theory suggests a weakly interacting massive particle, or WIMP, may be the dark matter minibeast. Hundreds of thousands of these could be flying through our fingertips every second. To tell whether they’re there, Cham and hundreds of scientists are building detectors: Huge vats of liquid xenon in underground caverns. Bond villain-esque lairs don’t come cheap, and listener Peter’s query is valid – what if dark matter goes the same way as the aether, an all-permeating (and ultimately non-existent) material that was hypothesised to carry light through the vacuum of space? Astrophysicist Katy Clough reiterates that experiments are the way to test predictions. Building a picture of how gravity works continues to take many people enormous effort, but this is the scientific process.

A Weighty Matter Part 1
The doctors investigate a millennia-old query, as listener Emma in New Zealand asks, ‘How does gravity pull us?’. People have been thinking about how gravity works for a very long time. Way longer than when that particular apple almost certainly didn’t fall on the head of Isaac Newton. Cosmologist Andrew Pontzen begins guiding us through our journey by taking us back to the almost entirely incorrect writings of ancient Greeks. We then fast forward past Galileo and Newton, and throw in an extra dimension. Using an all-too-believable analogy where some merry cyclists suddenly ride into a meteor crater, astrophysicist Katy Clough tells us how Einstein’s spacetime works. Limitations of analogies accepted, this explains some of the observations that didn’t fit with Newton’s workings alone. But there are other snags with our understanding of gravity, both at the very small quantum scale and the very large galactic scale. Physicist Chamkaur Ghag introduces what scientists think may account for some of these issues: The mysterious dark matter.

The Flying Clock and the Stopped Watch
Psychologist and presenter of All in the Mind, Claudia Hammond wrote the book ‘Time Warped – Unlocking the Mysteries of Time Perception’. She explains how emotion and memory are big factors in how time is perceived. She stresses how time can stretch and squeeze depending on whether you are looking backwards or forwards. And she explains how lockdown has warped time in different ways for different people. Professor David Eagleman, from Baylor College of Medicine in Houston, conducted a very famous experiment on time dilation, to see whether time slows down when you are very frightened. He wanted to see whether people actually have increased time resolution during a terrifying moment, and tested whether his students actually see in slow motion when they leapt off a tall building (in a safe manner). Professor Marc Whitman is a neurologist who has spent his career looking for the clock in our brains. He says that time is dealt with in many parts of the brain, with some parts dealing with different durations, from milliseconds to decades. Katya Rubia is Professor of Cognitive Neuroscience at Kings College London and is an expert on time perception in children with ADHD. She links the impulsiveness of children with Attention Deficit Hyperactivity Disorder to problems with time perception and has found that the pre frontal lobe, which is key for perceiving time is both functionally and structurally different in children with the disorder, which means that time goes much slower for them. This goes some way to explain their impatience and inability to sit still. Produced by - Fiona Roberts Presented by – Hannah Fry and Adam Rutherford A BBC Audio Science Unit Production

The Mosquito Conundrum
The doctors put mosquitoes on trial, as listener Cathy in the UK asks, ‘What is the point of mosquitoes?’ in response to our show about wasps. Mosquitoes have undeniably played a role in killing millions of people. Malaria is the single biggest cause of death in human history. But Erica McAlister, senior curator of flies and fleas at the UK’s Natural History Museum, reveals that not all mosquitoes are interested in biting us for a blood meal, or are involved in transmitting disease. Only the females of about 10 species are the most problematic for humanity, from around 3600 true species of mosquito. Limited research indicates that many play important roles in ecosystems, for example as pollinators on land and as food sources during their larval stage in aquatic environments. Nonetheless, those roughly 10 species cause devastating disease. Kate Jones’ research at University College London examines the interface of ecology and human health. Malaria and dengue fever alone cause over 300 million infections annually. And there are many more diseases transmitted by mosquitoes: Zika, West Nile fever, Yellow fever, Japanese encephalitis – the list goes on, and with urbanisation and climate change, the picture is constantly changing. So what can be done? Should we try to annihilate the disease-carrying species? Insecticide use has historic and ongoing controversy, as the difficulties of needing to stop deaths in the short term risks longer term environmental damage, with unforeseen and possibly greater consequences for humanity. So Adam turns to new, genetic technology with zoologist Matthew Cobb. Can and should we modify mosquitoes to wipe themselves out, by wrecking local populations with sterile males, or use a technique called a gene drive to perpetuate debilitation through generations? Or could life find a way to evolve past our attempts at control, and cause greater problems? The doctors deliberate and try to decide a verdict on mosquitoes’ fate.

The Scientific Exploration of Astrology
Astrology – could there be something to it? asks Dan from Australia. Rutherford and Fry investigate the science that has investigated astrology. Professor Richard Wiseman, (sceptical of all things paranormal and a Virgo) and Professor in the Public Understanding of Psychology at the University of Hertfordshire, explains the long history of the scientific investigation of astrology. He has also run his own experiments to test whether astrology can help you play the stock market and to investigate if people born in the summer are luckier than those born in the winter – the results may surprise you. Journalist and author, Jo Marchant (Leo and fascinated non-believer) has written all about the history of astrology in her new book – 'The Human Cosmos – A Secret History to the Stars'. In the beginning astrology and astronomy were one and the same. She explains how astrology flourished with the elite and ruling classes of ancient Babylon, Egypt and Greece. Data scientist, Alex Boxer (Taurus and cautious astrology tourist) explains that astrology may have been humanity's first attempt to predict the future with algorithms, something we’re doing more and more of now. In his book, ‘A scheme of heaven, astrology and the birth of science’, he describes how astrological and scientific algorithms are all just big data science looking for patterns. The issue lies in what that data is. Presenters: Hannah Fry (Pisces) & Adam Rutherford (Capricorn) Producer: Fiona Roberts (Libra)

The Noises That Make Us Cringe
Why do some people find noises like a fork scraping a plate so terrible? asks Findlay in Aberdeenshire. Rutherford and Fry endure some horrible noises to find out the answer. Warning - This episode contains some horrible sounds Trevor Cox, Professor of Acoustic Engineering at the University of Salford, has run experiments to find out the worst, most cringe-making sound. He divided horrible sounds into three categories: scraping sounds, like nails down a blackboard; disgusting sounds like a snotty sniffy nose; and sounds that make us cringe because of what we associate them with, like the dentist’s drill. All horrible sounds have some sort of association whether it’s a primal scream or fear of catching a disease, and they’re dealt with in the ancient part of the brain – the amygdala. Professor Tim Griffiths is a Cognitive Neurologist at Newcastle University’s Auditory Cognition Group. He has been studying people with misophonia, a condition where ordinary, everyday sounds, such as someone eating or breathing causes a severe anxiety and anger response. Misophonia may affect around 15% of the population and Tim thinks that different parts of the brain – the insula and the motor cortex - are involved in this fight or flight response to seemingly innocuous sounds. Cat Thomas’s job is to make horrible sounds. She is a foley artist at Boompost. If you watch Call the Midwife or Peaky Blinders, all the incidental sounds are created by Cat and her team. She also created some of the sounds for the horror film Camilla, which involved evisceration and disembowelling with the aid of some squishy oranges and bananas. Adam Rutherford and Hannah Fry try their own horror sounds when they chop off a finger with the aid of some large pasta shells, an orange and a knife.
